COMPOSITE BUILDING PRODUCTS BOUND WITH CELLULOSE NANOFIBERS |
摘要 |
<p>Building materials are generated by the simple mixing of cellulose nanofiber (CNF) slurry with typical wood-derived material such as wood meal, optionally with mineral particulate materials, and dried. Particle boards are made with wood meal particulates; wallboards are made with wood particulates and mineral particulates; paints are made with pigment particulates; and cement is made with aggregate particulates. The particle board samples were tested for fracture toughness. The fracture toughness was found to be from 20% higher up to ten times higher than the typical value for similar board, depending on the formulation. For cases of 20% by weight cellulose nanofibers and 80% wood, the fracture toughness was more than double that of typical particle board. The process sequesters carbon and oxygen into the building product for its lifespan - typically decades -and avoid releasing CO2 into the atmosphere.</p> |
